给定一个正整数 n，请输出 n 位格雷码序列。 第 i 个格雷码（i 从 0 开始编号）定义为 g(i) = i xor (i >> 1), 其中 xor 表示按位异或，>> 表示右移。请依次输出 i = 0, 1, ..., 2^n - 1 对应的 g(i)，每个格雷码用恰好 n 个字符的二进制串表示，不足 n 位时在高位（左侧）补 0。

给出两个非负整数 a 和 b，请计算它们的乘积 a × b。 两个整数都以十进制形式给出，各自的位数都可能达到 200 位，乘积的位数可能超过 400 位，已经超出普通整型的表示范围。请使用高精度方式完成计算，保证结果的每一位都准确无误。 输入格式 输入共两行 ...
